HIGHNVD 7.57.5—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 70% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Grav is a file-based Web platform. Prior to 1.8.0-beta.27, having a simple form on site can reveal the whole Grav configuration details (including plugin configuration details) by using the correct POST payload to exploit a Server-Side Template (SST) vulnerability. Sensitive information may be contained in the configuration details. This vulnerability is fixed in 1.8.0-beta.27.
